Helpful Comparison Insights
When looking for the Best Spark Plugs For 2017 Honda Accord, your choice really comes down to which engine you have and whether you need longevity or are fixing an ignition system issue.
L4 (2.4L) vs. V6 (3.5L) Engine Needs:
If you have the standard 2.4L L4 engine, you need a 4-pack of plugs. If you have the powerful 3.5L V6, you must purchase a 6-pack, such as the NGK G-Power option.
Longevity vs. Performance:
For maximum longevity (100k+ miles) on the 2.4L, the 4 pc NGK Laser Iridium Spark Plugs are the top choice, as they mirror the factory requirements perfectly. If you want maximum ignitability and performance, the NGK LKAR7BIX-11S Iridium IX provides a sharper throttle response.

Best Spark Plugs For 2017 Honda Accord: Comprehensive FAQ
Q1: What is the recommended spark plug type for the 2017 Honda Accord 2.4L engine?
For the 2.4L four-cylinder engine, Honda recommends using iridium spark plugs, which are generally standard (or upgraded) on modern engines. Iridium offers superior heat resistance and longevity compared to traditional platinum or copper, typically providing a 100,000-mile change interval. Look for quality options like NGK Laser Iridium or Iridium IX.
Q2: How often should I change the spark plugs in my 2017 Honda Accord?
The factory maintenance schedule for the 2017 Accord, especially when using high-quality iridium spark plugs, usually calls for replacement around 100,000 to 105,000 miles. However, if you notice symptoms like rough idling, decreased fuel economy, or a check engine light indicating an engine misfire, they may need replacement sooner.
Q3: Do I need to replace the ignition coils when I replace the spark plugs?
While not strictly mandatory every time, replacing the ignition coils (UF712 reference) is highly recommended if your 2017 Accord is high-mileage (over 100k) or if you are experiencing misfires. Worn spark plugs increase the demand on the coils, causing premature failure. Replacing both together (as seen in bundled kits) ensures optimal ignition system performance and reduces the chance of future ignition problems.
Q4: What gap size should the new spark plugs be set to?
The spark plug gap is a critical specification for optimal engine performance. While it’s best to confirm with your owner’s manual or a specific plug manufacturer’s reference, most 2017 Honda Accord 2.4L L4 engines require a gap setting in the range of 0.040 to 0.044 inches. Most iridium plugs come pre-gapped, but always check before installing.
Q5: Is NGK better than other brands for my Honda Accord?
NGK is one of the primary Original Equipment (OE) suppliers for Honda spark plugs, making them a consistently safe and reliable choice for the 2017 Accord. While brands like Denso also make excellent products, using genuine NGK parts ensures the correct heat range, fitment, and material quality that the Honda Accord engine was designed for.
Q6: Can using the wrong spark plugs cause poor fuel efficiency?
Absolutely. If you use plugs with the incorrect heat range, improper gap, or worn-out materials, the combustion process will be incomplete. This leads to poor fuel economy, reduced power output, and potential carbon buildup. Choosing the specified iridium plugs ensures you maintain maximum efficiency.
